You’re staring at a red, angry-looking welt on your arm. It hurts. It burns. Naturally, you’ve pulled out your phone and typed "picture of wasp bite" into the search bar, hoping to figure out if you’re about to have a medical emergency or if you just need an ice cube and a distraction.
Most people use the term "bite," but wasps actually sting. They don't want your blood. They want you away from their nest. Unlike honeybees, which have barbed stingers that get stuck in your skin (effectively disemboweling the bee when it flies away), wasps have smooth stingers. This means a single wasp can jab you multiple times in a matter of seconds.
It’s nasty stuff.
What a typical wasp sting looks like on your skin
If you look at a picture of wasp bite (or sting) from a standard reaction, you’ll notice a very specific pattern. Usually, there is a central white spot. This is where the stinger actually pierced the flesh. Surrounding that tiny white dot is a red, raised welt. The medical term for this is a "wheal." It looks a bit like a mosquito bite that went to the gym and got way too aggressive.
The redness isn't just a surface stain. It’s localized inflammation. Your body is reacting to the melittin and other toxins in the wasp venom. Within minutes, the area might swell to the size of a quarter. Sometimes it’s bigger. It’ll feel hot to the touch.
It pulses.
Dr. Howard Levy, a noted clinical expert in immunology, often points out that the initial sharp pain usually gives way to a dull, throbbing ache that can last for hours. If you’re looking at your skin and the redness is spreading rapidly beyond the initial site—say, it started on your finger but now your whole hand is crimson—you’re moving out of "normal" territory and into a "Large Local Reaction" (LLR).
About 10% of people get these LLRs. They aren't necessarily dangerous, but they are incredibly uncomfortable. The swelling might peak at 48 hours and hang around for a week. It’s often mistaken for cellulitis (a bacterial skin infection), but if it happened right after the sting, it's almost certainly just the venom doing its thing.

Why the "picture" varies by person
Your skin type and the specific wasp species matter. A yellowjacket sting often looks different than a paper wasp sting. Yellowjackets are notorious for being "dirty" stingers; they spend time around trash and rotting fruit, so the risk of a secondary infection is slightly higher.
Then there’s the site of the sting. A sting on the soft tissue of your eyelid will look terrifyingly different than a sting on the calloused palm of your hand. On the face, the swelling can be so intense that it closes the eye completely. Don’t panic—unless you’re having trouble breathing.
Identifying the culprit: Was it a wasp or something else?
People get confused. They see a red bump and assume. But if you didn't see the insect, you have to play detective with the marks left behind.
- Honeybees: You’ll usually see the stinger still in the wound. It looks like a tiny, dark splinter with a pulsating sac attached.
- Hornets: These are basically wasps on steroids. The sting site will be much larger, and the pain is often described as "electric" or "searing."
- Spiders: A spider bite usually has two distinct puncture marks. Wasp stings have one.
- Mosquitoes: These are itchier than they are painful. They lack that central "white eye" that characterizes a fresh wasp sting.
The venom of a wasp is a complex cocktail. It contains histamine, which causes the itching and swelling, and hyaluronidase, which helps the venom spread through your tissue. It’s an efficient delivery system for pain.
When the picture becomes an emergency
We need to talk about anaphylaxis. It’s rare, but it’s real. If you are looking at a picture of wasp bite on your body and you also feel like your throat is closing, call emergency services immediately.
Ignore the skin for a second. Look at the "big picture" of your symptoms:
- Are you wheezing?
- Do you feel dizzy or faint?
- Is your heart racing like you just ran a marathon?
- Do you have hives breaking out on parts of your body nowhere near the sting?
This is a systemic reaction. Your immune system is overreacting and dropping your blood pressure while constricting your airways. This is where an EpiPen (epinephrine) comes into play. According to the Journal of Asthma and Allergy, prompt administration of epinephrine is the only way to reverse these symptoms.

Real-world treatment: Beyond the old wives' tales
You’ve probably heard about putting a penny on it. Or tobacco juice. Or baking soda paste.
Honestly? Most of that is nonsense.
The venom is injected deep into the skin. Rubbing stuff on the surface won't "neutralize" it. The acidity or alkalinity of the treatment doesn't matter because the venom isn't just sitting there waiting to be balanced out by a chemistry experiment.
Here is what actually works:
First, wash the area with plain soap and water. You want to get rid of any bacteria the wasp might have left behind. Use cold water. Cold is your best friend. It constricts the blood vessels and slows the spread of the venom.
Take an antihistamine. Diphenhydramine (Benadryl) is the classic choice, but it’ll make you drowsy. If you need to stay awake, Cetirizine (Zyrtec) works well too. This addresses the histamine the wasp just pumped into you.
Hydrocortisone cream (1%) can help with the itch later on. But don't expect it to work instantly. It takes time to penetrate the dermis.

If the pain is unbearable, Ibuprofen is better than Acetaminophen here. Why? Because Ibuprofen is an anti-inflammatory. It attacks the swelling from the inside out.
Long-term marks and scarring
Sometimes, a wasp sting leaves a "memory."
A week after the sting, you might notice a small, hard lump under the skin. This is often just a bit of scar tissue or a localized granuloma. It’s your body’s way of walling off the damaged tissue. It usually fades over a few months.
In some cases, the skin might hyperpigment. This means the spot stays dark—brown or purplish—long after the redness goes away. This is more common in people with darker skin tones. It’s not permanent, but it can be annoying.
Specific actions you should take right now
If you’ve just been stung and you’re staring at that picture of wasp bite forming on your skin, follow these steps in order.
- Move away. If you got stung once, there’s a high chance the wasp released "alarm pheromones." This tells its buddies that you are a threat. Leave the area immediately to avoid a swarm situation.
- Ice it. 10 minutes on, 10 minutes off. Don't put ice directly on the skin; wrap it in a paper towel. This reduces the "fire" feeling.
- Elevate. If the sting is on your leg or arm, keep it raised. This uses gravity to keep the swelling down.
- Monitor. Check the size of the redness. Use a pen to draw a circle around the edge of the red area. If the redness expands significantly past that line in the next few hours, it’s time to see a doctor.
- Stop scratching. It's hard. I know. But scratching introduces bacteria from your fingernails into the wound. That’s how a simple sting turns into a staph infection.
If the swelling doesn't start to go down after 48 hours, or if you start running a fever, the sting might have become infected. At that point, you’ll need a round of antibiotics, which only a healthcare provider can prescribe.
Watching the site closely is the best thing you can do. Most wasp stings are just a painful reminder that nature has defenses. They are uncomfortable, ugly, and itchy, but for the vast majority of the population, they are a temporary nuisance rather than a life-threatening event. Keep the area clean, keep it cool, and let your immune system do the heavy lifting.
